• The influence of microscale surface roughness on water-droplet contact electrification ﻿

(Peer reviewed; Journal article, 2019)
When water comes in contact with a hydrophobic fluoropolymer, a triboelectric charge tends to form on the surface. Here, it is investigated how the triboelectric charge formed upon contact with water drops depends on the ...
• Influence of Residual Oil on Polymer Injectivity ﻿

(Master thesis, 2017-06-22)
Because a significant fraction of the world’s light oil reservoirs has already been produced, the technical and economic challenges of developing heavy oil fields is now unavoidable [1]. Water flooding has proven to be a ...
• Influence of Salt Concentration on Charge Transfer When a Water Front Moves across a Junction between a Hydrophobic Dielectric and a Metal Electrode ﻿

(Journal article; Peer reviewed, 2020)
An energy-harvesting device based on water moving across the junction between a hydrophobic dielectric and a metal electrode is demonstrated. The charge transfer due to contact electrification as the junction is dipped ...
• Insight into particle production mechanisms via angular correlations of identified particles in pp collisions at $\sqrt{s}=7$ TeV ﻿

(Peer reviewed; Journal article, 2017-08)
Two-particle angular correlations were measured in pp collisions at $\sqrt{s} = 7$ TeV for pions, kaons, protons, and lambdas, for all particle/anti-particle combinations in the pair. Data for mesons exhibit an expected ...
• Instrumentering av eksperimentell vannkolonne for studier av mikroalgers vertikalforflytning ﻿

(Master thesis, 2013-05-31)
Alger er viktig som primærprodusent i det marine økosystem. Det er derfor viktig at det oppnås større forståelse for hvordan alger lever og dør. For å kunne oppnå denne forståelsen må det gjøres tester og eksperimenter på ...
• Integrating Cognitive Learning Strategies into Physics Instruction : Developing students’ approaches to physics and learning ﻿

(Doctoral thesis, 2021-03-24)
Introductory physics courses are obligatory for many disciplines outside of physics. As experienced by many students, they are notoriously difficult, often with high failure rates. Many students, whether they passed or ...
• Integrating effective learning strategies in basic physics lectures: A thematic analysis ﻿

(Journal article; Peer reviewed, 2021)
Introductory mechanics is an obligatory course for many disciplines outside of physics and the failure rate is often high. Even the students who pass the course often fail to achieve the main learning goal: The conceptual ...
• Integration and design for the ALICE ITS readout chain ﻿

(Master thesis, 2018-06-26)
ALICE and its Inner Tracking System detector in the LHC at CERN will undergo a major upgrade during its second long shutdown taking place in 2019 and 2020. New silicon sensors called ALPIDE will be utilized, which requires ...
• Intensity asymmetries in the dusk sector of the poleward auroral oval due to IMF Bx ﻿

(Peer reviewed; Journal article, 2014-12)
In the exploration of global-scale features of the Earth's aurora, little attention has been given to the radial component of the Interplanetary Magnetic Field (IMF). This study investigates the global auroral response in ...
• Inter-patient variations in relative biological efectiveness for craniospinal irradiation with protons ﻿

(Journal article; Peer reviewed, 2020)
Cranio-spinal irradiation (CSI) using protons has dosimetric advantages compared to photons and is expected to reduce risk of adverse effects. The proton relative biological effectiveness (RBE) varies with linear energy ...
• The interaction between transpolar arcs and cusp spots ﻿

(Peer reviewed; Journal article, 2015-11-25)
Transpolar arcs and cusp spots are both auroral phenomena which occur when the interplanetary magnetic field is northward. Transpolar arcs are associated with magnetic reconnection in the magnetotail, which closes magnetic ...
• Interaction of Cold Streaming Protons with the Reconnection Process ﻿

(Journal article; Peer reviewed, 2020)
We employ a 2.5D particle-in-cell simulation to study a scenario where the reconnection process captures cold streaming protons. As soon as the tailward streaming protons become involved, they contribute to the overall ...
• Interaction of piezoelectric transducer excited ultrasonic pulsed beams with a fluid-embedded viscoelastic plate. Finite element modeling, angular spectrum modeling and measurements ﻿

(Doctoral thesis, 2014-03-28)
• Interaction of the hydrogen atom with laser fields: a study of relativistic effects in ionization processes ﻿

(Master thesis, 2018-06-14)
• Interactions between CO2, saline water and minerals during geological storage of CO2 ﻿

(Doctoral thesis, 2006-06-30)

(Peer reviewed; Journal article, 2011-01-07)
We demonstrate a feature of the Rydberg blockade mechanism which occurs between two initially excited circular Rydberg atoms. When both atoms are exposed to weak time-dependent electric fields, it is shown that the intrashell ...
• Intercomparison of the POES/MEPED Loss Cone Electron Fluxes With the CMIP6 Parametrization ﻿

(Peer reviewed; Journal article, 2019)
Quantitative measurements of medium energy electron (MEE) precipitation (>40 keV) are a key to understand the total effect of particle precipitation on the atmosphere. The Medium Energy Proton and Electron Detector (MEPED) ...
• Interface Design for the Gigabit Transceiver Common Readout Unit ﻿

(Master thesis, 2016-06-01)
The future upgrade of the Large Hadron Collider accelerator, the High-Luminosity LHC, has its goal of increasing the beam luminosity by ten times. This will lead to a corresponding growth of the amount of data to be treated ...
• Interplanetary Magnetic Field Bx Component Influence on Horizontal and Field-Aligned Currents in the Ionosphere ﻿

(Peer reviewed; Journal article, 2018-05)
Statistical analyses have shown that the sunward component of the interplanetary magnetic field, Bx (Geocentric Solar Magnetospheric), moderately but significantly affects the auroral intensity. These observations have ...
